IEC 61643-11 is an international standard that specifies the requirements, testing, and performance criteria for part 11, which pertains to low-voltage surge arresters connected to low-voltage distribution systems (up to 1,000 V AC). It aims to ensure surge arresters provide reliable protection against transient overvoltages caused by lightning or switching surges in electrical distribution networks.
A surge arrester is a device designed to protect electrical equipment from overvoltage transients by diverting surge current safely to the ground. It limits the voltage across the protected equipment, preventing damage caused by lightning strikes, switching operations, or other transient phenomena.
